On-chip efficient storage of electrical energy with negative super-capacitance in 2D material systems

We propose the combination of two performance boosters: (i) negative capacitance principle, exploiting ferroelectricity in doped high-k dielectrics, as developed and validated in 2D devices of our ERC Advanced grant Millitech, and, (ii) 2D graphene electrodes to enhance the performance of supercapacitors in on-chip 2D material systems, in an innovative device called N-supercap.

While negative capacitance was until now explored mainly for digital and analog low power electronics, we propose to exploit NC in ferroelectric/dielectric/2D capacitors for on-chip energy storage to support autonomous sensory nodes.

This will result in a versatile energy storage systems for IoT Edge AI systems, to enable a large scale deployment in tens of billions without maintenance costs, in a scalable and eco-friendly technology.

The proposed PoC will serve as first step in the creation of startup that will aim at using such N-supercaps in various IoT node applications in environmental, industrial and healthcare monitoring.

We have set a team of experts to exploit this technological breakthrough into the creation of a startup, based on a road to commercialization.
